HS(G)158 states, “Health and safety law requires that plant and equipment is maintained in a safe condition. It is essential that flame arresters are well maintained. They should be covered by a program of regular inspection and maintenance so they continue to be effective.”

It also goes on to say, “Keep records of the specification of each arrester, its location and its maintenance history.” These records help to identify if the arrester is suitable for the media that it is protecting. Should the process conditions be changed it can then be easily identified if the flame arrester fitted remains suitable for the new conditions.
